Welding procedure
MIG/MAG welding
Special, latched with superpulse
Step 1
• Press and hold torch trigger
• Shielding gas is expelled (gas pre-flows)
• Wire feed motor runs at "creep speed".
• Arc ignites after the wire electrode makes contact with the workpiece, welding current is flowing (start
program P
START
Step 2
• Release torch trigger
• Slope on main program P
• Start the super pulse function beginning with main program P
The welding parameters change at the specified times between main program P
main program P
Step 3
• Press the torch trigger.
• Super pulse function is ended.
• Slope in the end program P
Step 4
• Release torch trigger
• WF motor stops.
• Arc is extinguished after the preselected wire burn-back time expires.
• Gas post-flow time elapses.
6.1.7.2 Automatic cut-out
Once the fault periods have elapsed, the automatic cut-out stops the welding process when it has been
triggered by one of two states:
• During ignition
5 s after the start of the welding process, no welding current flows (ignition error).
• During welding
The arc is interrupted for more than 5 s (arc interruption).
